1.4.2 How to install a DIMM Module

1. The DIMM socket has a “ Plastic Safety
Tab”, and the DIMM memory module has
an “Asymmetrical notch”, so the DIMM
memory module can only fit into the slot
in one direction.

2. Push the tabs out. Insert the DIMM
memory modules into the socket at a
90-degree angle, and then push down
ver tica lly so th at it will f it into t he place.

3. The Mounting Holes and plastic tabs
should fit over the edge and hold the
DIMM memory modules in place.

1.5 Slots

The slots in this motherboard are designed to hold expansion cards and connect them to
the system bus. Expansion slots are a mean of adding or enhancing the motherboard's
features and capabilities. With these efficient facilities, you can increase the
motherboard's capabilities by adding hardware that performs tasks that are not part of
the basic system.

1.5.1 ACR (Advanced Communication Riser) Slot

The ACR specification is an open Industry Standard Architecture, and it defines a
hardware scalable riser card interface, which supports audio and modem only.

1.5.2 AGP (Accelerated Graphics Port) Slot

Unlike the mouse ports, keyboard ports and printer ports, this motherboard does not
have built in video facilities; and therefore, requires a video card for one of the

expansion slots. Your monitor will attach directly to that video card. This
motherboard supports video cards for PCI and ISA slots, but it is also equipped
with an Accelerated Graphics Port (AGP). An AGP card will take advantage of
AGP technology for improved video efficiency and performance, especially with
3D gra phics.

1.5.3 CNR (Communication Network Riser) Slot

The CNR specification is an open Industry Standard Architecture, and it defines a
hardware scalable riser card interface, which supports audio and modem only.

1.5.4 PCI (Peripheral Component Interconnect) Slots

This motherboard is equipped with 5 standard PCI slots. PCI stands for Peripheral
Component Interconnect, and it is a bus standard for expansion cards, which has

supplanted the older ISA bus standard in most parts. This PCI slot is designated as
32 b its.

1.6 Connectors, Headers & Jumpers

The connectors, headers and jumpers introduced below provide you lots of
capabilities such as power supply, front panel signal revelation, IDE hard disk
connection, floppy disk connection, Wake On LAN function and USB connection.
Noticeably, a jumper has two or more pins that can be covered by a plastic jumper
cap, allowing you to select a different system options.

SPK (Speaker Connector)

An offboard speaker can be installed on the motherboard as a manufacturing option.
It can be connected to the motherboard at the front panel connector. The speaker

(onboard or offboard) provides error beep code information during the Power On
Self-Test when the computer cannot use the video interface. The speaker is not
connected to the audio subsystem and does not receive output from the audio
subsystem.

Chapter 1 Motherboard Description

RST (Reset Button)

This connector can be attached to a momentary SPST switch. This switch is usually
open, and when it is closed, it will cause the motherboard to reset and run the POST
(P ower O n Self T es t).

POW-LED (Power LED Connector)

This connector can be attached to an LED on the front panel of a computer case.
The LED will illuminate while the computer is powered on.

HLED (Hard Drive LED Connector)

This connector can be attached to an LED on the front panel of a computer case.
Th e LED w ill flicker durin g disk ac t ivity where it is o n ly a pplied to thos e IDE
drives directly attached to the system board.

IR (Infrare d Connector)

This connector is used to attach to an infrared sensing device. After the IrDA
interface is configured, connectionless data transfer to and from portable devices
such as laptops making PDAs is possible.

SLP (S lee p/Green B utto n)

This connector is used to conserve energy by powering down the monitor and the
hard disk when is not in use. To configure this option, you need to connect a button
from the front panel to this sleep button. Depressing the button will power down
the monit or and th e har d driv es until th e sys tem is invoked by any keyboard activity,
mouse activity, modem activity or when the sleep button is depressed again. APM
(Advanced Power Management) must be enabled in the system BIOS and the APM
driver must be loaded.

ON/OF F (P owe r B utto n)

This connector can be attached to a front panel power switch. The switch must
pulled the Power Button pin to ground for at least 50 ms to signal the power supply
to switch on or off. (The time required is due to internal debounce circuitry on the
system board). At least two seconds must pass before the power supply will
recognize another on/off signal.
